Abstract

Ground based emission spectroscopy measurements are performed in the high arctic. A commercial uncooled FTIR interferometer has been sued. The emission spectra of the polar atmosphere are collected to examine the variation of trace gases in the dark wintertime. The emission of these trace gases is calculated by the FASCOD3 algorithm. Additionally tropospheric aerosols have to be considered in the analysis. The concentration variations of the gases and aerosols are due to the absence of photolytical reactions in the wintertime and to transport of polluted airmasses from the midlatitudes to the Arctic.
